The Color Red and Performance Color affects us in many ways. For example, experiments have shown that the color red appears to enhance men's attraction to women. Previous studies have also shown that athletes competing against an opponent wearing red perform worse, and students exposed to red before a test perform worse. A recent study2 states that "red is hypothesized to impair performance on achievement tasks, because red is associated with the danger of failure." In the study, US college students were asked to solve 15 moderately difficult, five-letter, single-solution anagrams during a 5-minute period. Information about the study was given to participants in either red, green, or black ink just before they were given the anagrams. Participants were randomly assigned to a color group and did not know the purpose of the experiment, and all those coming in contact with the participants were blind to color group. The red group contained 19 participants and they correctly solved an average of 4.4 anagrams. The 27 participants in the green group correctly solved an average of 5.7 anagrams and the 25 participants in the black group correctly solved an average of 5.9 anagrams. Work through the details below to test if performance is different based on prior exposure to different colors. 1"Color Red Increases the Speed and Strength of Reactions," Science Daily, sciencedaily.com, June 2, 2011. 2Elliot, A., et al., "Color and Psychological Functioning: The Effect of Red on Performance Attainment," Journal of Experimental Psychology: General, 2007; 136(1): 154-168.
